Layout of the DC bus power supply

The power supply of the DC bus for must be selected specific to the application (e.g. iSA, iC, KE, KEN, KES) and must take the following points into account:

• Continuous rated current, which the power supply must provide
• Simultaneity factor of the connected drives
• Overload current and time duration
• Motor / regenerative operation
  • Current regeneration (if available)
  • Brake resistor
